Interstellar Manual

You can use Interstellar as a secure digital wallet to securely store your fiat and crypto-currencies. As examples, Interstellar will help you securely store your Bitcoin, Stellar Lumens or any other Stellar based asset.

Another neat feature of Interstellar is its support for multiple accounts, which is essential when you want to have different accounts for separate transactions.

Multisig(multiple signatures) will protect your account from thefts and loss.

Multisig is technology that forces your account to require multiple signatures before performing transactions. You could, for example, set up a 2 of 3 multisig account where 2 signers out of 3 are required to approve a payment before it is issued out.
